The article deals with the question of determining from what distance a shot was made from a firearm. After determining the distance, a sector is set in which the shooter was possibly located. The solution to this issue is carried out in several ways.
The most common method is to sight, the essence of which is to reproduce the line of flight of the projectile for the existing damage on the obstacles. To do this, take two distances from one another, formed by one projectile, or a blind damage with a deep bullet channel.
Establishing the distance at which the shot was fired makes it possible to determine a wider spectrum of detection of traces and other material evidence, such as shells, bullets, soot, oil, and other traces.
A preliminary trace analysis makes it possible to establish the mechanism of the crime committed, discard the version of whether the accident occurred, suicide or to confirm the version of the murder.
Key words: the place of shot, input-output hole, distance of shot, sighting.
